CENTRLFUGAL GUN Filed Nov. 26, 1929 2 Sheets-Sheet 1 jectile will be released. Thus the projectiles are released successively, one at each revolution of the rotating barrel, and each projectile will be released in exactly the same position and will be impelled by equal centrifugal force to that of the other projectiles so as to ensure accuracy in the timing and propulsion of the projectiles. It will be readily seen that by angularly adjusting the cam plate 1.1 the position at which the projectile is released can be determined at will. i

In the modified form shown in Fig. 3, the retaining member is in the form of a twoarmed lever, one arm 20 of which projects into the barrel through a slot 21 th rein, while the other arm 22 extends outwardly and rests against the under side of an annular flange 23. The two-armed lever is pivotally mounted at 24 on the barrel, of the gun, and it is so arranged that its weight tends to hold it in a position in which the arm 20 projects into the barrel so as to arrest the projectile until the latter has acquired sufficient centrifugal. force to turn the two-armed lever about its pivot. Alternatively instead of arranging that the weight of the two-armed lever holds it in the position stated, a spring may be provided for this purpose. In this case, in order to control the position at which the twoarmed lever is turned to release the projectile,

the arm 22 bears against the annular flange 23 forming the retaining control means until this arm 22 comes opposite a notch 25 which permits the two-a"med lever to turn. The

notch 25 is provided with an inclined portion 26 which serves positively to ensure the return of the catch to its projecting position as in the previous construction. A bracket 27 having an inwardly extending part 28 is provided below the inclined part of the notch 26 to prevent the retaining member from being released except at the notch 25.

In Fig. 4 the arrangement is similar to Fig. 3, but in this case a multi-armed retaining member 31 is provided which is rotatably mounted upon the fixed pin 32. This member 31 has four arms marked 30, one of which projects through a slot 33 in the barrel and serves to arrest the projectile as before. The retaining member may be so mounted that its inertia may act to arrest the projectile until the latter has acquired sutlicient cetr fugal force or a spring may be provided for this purpose. The retaining control means in this case comprise an annular flanged mem ber 34 having a notch 35.

The invention also applies to guns having two barrels, an application of the construction as described with reference to Figs. 1 and 2, to which, is shown in Figs. 5, 6 and 7. In this case like reference numerals are employed to denote like parts with those in Figs. 1 and 2. Two leaf spring retaining members 5 and 5 are provided, one for each barrel. These members 5, 5 are fixed at one end 6 to the breech of the barrel and are free at their other ends 6. The free end of each member 5 01' 5 is spaced apart from the shaft about which the gun rotates and tends normally to project into the breech end of the barrel and thus arrest the projectiles at the breech end of each barrel. These retaining members are entirely independent the one of the other, and each acts in a similar way to retaining member 5 in Figs. 1 and 2. Each of said members 5, 5 is provided with projections 9 and 9 respectively. These projections 9 and 9 have laterally extending parts 38 and 38 for a purpose which will be hereinafter explained. In order to direct the projectiles to one barrel and cut off the other barrel, a guide 40 is provided having curved guide surfaces 41 and being rockably mounted on the pivote42. This guide member is connected by means of links 43 and 44 at its ends to the projections 9 and 9 on the retaining members 5, 5. The arrangement is such that the retaining member 5 as before stated. tends to arrest the projectile, such as that shown in dotted lines in 5 and marked 45, until the centrifugal force of this projectile has reached the required amount when the projectile tends to turn the spring 5 out of its projecting position. When this happens the projection 9 is moved down. This movement of the projection 9 is, however, normally pre' vented by engagement of the lateral extension 38 with the cam plate 46 until a point in the movement of the barrels is reached at which the projection 38 comes opposite to a slot 39 (Figs. 7, 8 and 9) in said cam plate. At this point the member 9 is permitted to move down so as to release the projectile, and in this movement the lateral. end 38 is brought into contact with an inclined cam surface 47 on the cam plate 46, which cam surface imparts further downward movement to the proj ection 9and causes this, through the link 43, to rock the guide member 40 over to the left hand side. While this is taking place the lateral extending end 38 of the project-ion 9 at the opposite side of the cam. plate 46, which has been held down by the cam plate 46, comes opposite to a slot 39 (Figs. 7, 8 and 9) and is allowed to move upwardly under the pull of the link 44. The cam plate is cut away at 47 to allow for the gradual upward movement corresponding to the downward .movement imparted to the end 38 by the incline47. This upward movement of the extending end 38 brings the spring 5 of the barrel 37, which had previously been depressed by the cam acting on the end 38', into its projecting position so that when the barrel 37 in its rotation gets into the position occupied by the barrel 36 in Fig. 5 and 6 the retaining member 5 and its associated parts will occupy the same position as the retaining member 5 in these figures, and the cycle of operations will be repeated.
